Statement Addition of water to a solutio...

Statement Addition of water to a solution containing solute and solvent changes its normality or molarity only.
Explanation The milli-equivalent and milli-moles of solutes are not changed on dilution.

A

(a)If both assertion and reason are true and the reason is the true explanation of the assertion.

B

(b)If both assertion and reason are true and the reason is not the correct explanation of the assertion.

C

(c )If the assertion is true but reason is false.

D

(d)If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
b
Meq. `=NxxV_("in mL")=("mass")/("Eq. mass")xx1000,`
No doubt N decreases with dilution but V increases and thus, Meq. Remains constant.
